# How many liters of hydrogen are obtained by dissolving 327 grams of zinc in sulfuric acid?

September 30, 2021 | education

| Zinc metal reacts with sulfuric acid to release hydrogen gas and form zinc sulfate. The reaction is described by the following equation:

Zn + H2SO4 = ZnSO4 + H2;

1 mole of metal reacts with 1 mole of acid. This synthesizes 1 mol of salt and 1 mol of hydrogen.

Let’s calculate the amount of zinc.

M Zn = 65 grams / mol;

N Zn = 327/65 = 5.031 mol;

During the reaction, 5.031 mol of hydrogen will be synthesized. Let’s calculate its volume.

To do this, multiply the amount of substance by the volume of 1 mole of gas.

V H2 = 5.031 x 22.4 = 112.7 liters;
